山西省新型储能发展指南发布

Core Viewpoint - The article emphasizes the need for the development of new energy storage in Shanxi Province to transition from "scale construction" to "high-quality development" in order to support the achievement of carbon neutrality goals and promote the healthy development of new energy storage technology and industry [1][14]. Group 1: Opportunities and Challenges in New Energy Storage Development - Opportunities: By 2030, Shanxi Province aims to achieve a renewable energy development target of 178 million kilowatts. The rapid growth of renewable energy installations increases the pressure on the power system for peak regulation and supply assurance, making new energy storage a key component in building a new power system and a solid guarantee for achieving carbon neutrality goals [2][15]. - Challenges: There are safety risks such as fire hazards due to thermal runaway when constructing new energy storage projects in densely populated areas with concentrated loads and limited renewable energy grid connections. Additionally, large-scale centralized energy storage may lead to limitations in the provincial 500 kV and 220 kV grid structure, resulting in operational restrictions and difficulties in ensuring project profitability [3][16]. Group 2: Energy Storage Capacity Evaluation System - An initial four-level evaluation system for energy storage capacity has been established based on grid carrying capacity, categorized as "Excellent, Good, Medium, and Poor" [4][17]. - Excellent: The current grid can accommodate a certain scale of energy storage without operational restrictions [7]. - Good: The grid will meet the connection requirements after the commissioning of planned grid projects, but may experience short-term operational restrictions before commissioning [8]. - Medium: Energy storage capacity exceeds the current grid carrying capacity, leading to frequent operational restrictions [8]. - Poor: Energy storage projects face long-term and high-frequency operational restrictions during peak load periods, impacting grid stability and project profitability [8]. Group 3: Development Recommendations - Based on the energy storage capacity evaluation system, recommendations for energy storage project connections in various districts and counties of Shanxi Province by 2026 have been proposed [5].
